DEVICES AND METHODS FOR COOLING MICROWAVE ANTENNAS |
摘要 |
Devices and methods for cooling microwave antennas are disclosed herein. The cooling systems (10) can be used with various types of microwave antennas. O ne variation generally comprises a handle portion with an elongate outer jacket extending from the handle portion. A microwave antenna is positioned within the handle and outer jacket such that cooling fluid pumped into the handle comes into contact directly along a portion of the length, or a majority of the length, or the entire length of the antenna to allow for direct convecti ve cooling. Other variations include cooling sheaths which form defined cooling channels around a portion of the antenna. Yet another variation includes passively-cooled systems which utilize expandable balloons to urge tissue aw ay from the surface of the microwave antenna as well as cooling sheaths which a re cooled through endothermic chemical reactions. Furthermore, the microwave antennas themselves can have cooling lumens integrated directly therethrough . |
